Investigating gasses

4th December 2018D Faircloth

In year 4, we have been learning about states of matter. Today we investigated gasses. We learned about how carbon dioxide was discovered by Joseph Priestly and how it is used to make fizzy drinks and fire extinguishers!

We wanted to discover which fizzy drink was the fizziest out of a selection of 4. To do this we weighed the drinks when they were fizzy, then we shook them 100 times until they were flat. After that, we weighed them again and worked out the difference in weight.

We found out that the cherryade was the fizziest as it had lost the most weight!
